         9 . A component according to  claim 1 , wherein the outer sheet material has a basis weight of between 20 gsm to 100 gsm, or 20 gsm to 80 gsm, or 30 gsm to 70 gsm. 
     
     
         10 . A component according to  claim 1 , wherein the outer sheet material comprises perforations. 
     
     
         11 . A component according to  claim 1 , wherein the component further comprises a cylindrical body of cellulose-based material. 
     
     
         12 . A component according to  claim 1 , wherein the cellulose-based material is paper, optionally wherein the paper is formed from wood pulp. 
     
     
         13 . A component according to  claim 11 , wherein at least one object is embedded in the cylindrical body of material. 
     
     
         14 . A component according to  claim 13 , wherein the at least one object comprises a tubular element and/or an aerosol-modifying agent release component. 
     
     
         15 . A component according to  claim 14 , wherein the at least one object comprises first and second tubular elements. 
     
     
         16 . A component according to  claim 15 , wherein the first and second tubular elements are separated by a gap between 0.5 mm and 6 mm, or between 1 mm and 3 mm, or between 2 mm and 5 mm, 
     
     
         17 . A component according to  claim 15 , wherein the first and second tubular elements are separated by a gap between 5 mm and 15 mm, or between 6 mm and 12 mm, or about 6 mm, about 7 mm, about 8 mm or about 9 mm. 
     
     
         18 . A component according to  claim 17 , wherein the body extends into said gap. 
     
     
         19 . A component according to  claim 1 , wherein the tubular body of cellulose-based material comprises gathered sheet material, and said gathered sheet material comprises cut out portions. 
     
     
         20 . An article for use in or as an aerosol provision system, the article comprising a component according to  claim 1 . 
     
     
         21 . A method of manufacturing a component for an article for use in an aerosol provision system, the method comprising the steps of:
 providing a feed of a first sheet material having a porosity of at least 200 CU;   forming an inner tubular element from the first sheet material;   providing a feed of cellulose-based material and a feed of a second sheet material;   gathering said cellulose-based material around the inner tubular element; and   wrapping the gathered cellulose-based material with the second sheet material to form a tubular body of cellulose-based material sandwiched between inner and outer sheet materials.   
     
     
         22 . An apparatus configured for manufacturing a component in accordance with  claim 1 , comprising:
